The present invention relates to. ae tool for holding a welding rod orsuch similar Idevice, and,

more particularly, toa welding rod usedin elecbecause of theelectricalcontactmade with theholding tool.

The holder now used for this purpose is commonly of the type in whichtwo jaws are pivoted to each other, one of which may be moved by aleverV against the action 'of a' spring fordisengaging the welding rodbeing held. Other` types of tools are of the ,pliers or forceps type,with some ratchet and locking means for adjustablyr holding the weldingmaterial in holder. While these devices are, the purpose, theynevertheless' are objectionable sometimes on account of their clumsinessand size and the fact that they have moving parts, and becausefrequently the lever or operating handle projects to one side andoftentimes interferes with the use of the tool in obstructed or narrowplaces.

The present invention overcomes these diculties and objections inproviding a Very simple holding tool for the welding rod. The tool hasno pivoted joints or levers and no projecting arms. It is symmetricalwith the longitudinal direction of the handle, comparatively smooth, andextremely easy to use or operate. The welding rod may be placed in theholding element at any desired angle and will be securely held withoutthe use of any clamping screw or other means which must be adjusted ortightened in applying the welding rod to the holder. In use as anelectrical welding tool, the cable or conductor is inserted through theend of the tool and is readily clamped in place. The tool may be left ona metal oor without any danger of arcing or turning over into such aposition that an arc can be struck.

Without further enumerating the other merits and advantages of thepresent invention, the invention will be described in connection withthe drawings illustrating an embodiment thereof, in which:

Fig. 1 shows a longitudinal sectional view through the holder;

Fig. 2 shows a section taken on the line Fig. 1;

Fig. 3 shows a section taken on the line 3-3 of Fig. 1;

Fig. 4 shows a detail view; and

.the jaws of a. satisfactory, for.

Fig. 5 shows. a 'modificationv of a detail. shown.

in Fig. 1.

ln the device indicatedin Figs:1 to 4, the holder is formedwith a handleI anda clamping-head 2, Awhichmay. be screwed into-a'wall 3 atlthe endof the holder as indicated at 4. As shown in- Fig. 1, the wall 3 is ofl,metallic material such asV steel vornironand actually forms an end capforfthe-v metallic tube 5,v whichis open at :the other endtoreceive the'cable I5:A The'tube Emay beof the same material as the'end-.3'and may beof` any-desired shape,,but preferably cylindrical or a regularpolygon insection. At the forward end of. the. tube, a small flange 'I extendsoutward. Thislange may be attached in any desiredmanner and-.may-cover(as vindicatedin Fig; cap 3 of theftube.

so=.-that tit xwillmaintain its. position land not roll. The weld rodholder 2 is provided at its end with a threaded stud 8, which may bescrewed into the end plate of the cap 3, but this may also bepermanently xed in place by welding or other means. Just in back of thethreaded stud is a collar 9 formed with flat sides, such as a hexagon,to permit the holder to be gripped easily by a wrench or pliers.Extending from the base 25 of the holder is a loop IU of sufficientlyheavy stock, of iron or steel preferably, to make it substantiallynon-yielding, although providing the usual spring flexibility inaccordance with the gauge of the loop. The form of the loop is indicatedin Fig. 1. The two sides I I and I2 join in a single stem with theportions Il and I2 of the loop extending substantially linear orslightly curved The outer end of the loop I3 is more or less arcuate inform for a sector of approximately The loop is symmetrical with a centeraxis in the plane of the loop and this axis is aligned with that of thepost or stud 8 and the collar 9. Extending from the base of the loop,where the linear sides Il and I2 come together, is a tongue or bar I4.This tongue or bar at its base lies partly in the plane of the loop butdeviates outwardly from this plane towards the end of the tongue,permitting a weld rod I5 to be wedged in between the face of the loopand the end of the tongue.

In Fig. l, three positions are shown for the weld rod I5. However, itisobvious that the rod I5 may assume an infinite number of positions inpractically all directions. The tongue lli tends to be round and thickerat the base and iiat and wider at the end I6, tapering gradually fromthe base away from the plane of the loop. The weld rod when in positionis supported by both sides of 1) the endl Aszindicated in Fig. 3, the;`flange `:may be in .theshape `of. a vregular polygon,`

maree The cable 6 is stripped of insulation as indicated at I1 and heldclamped to the inside of the tube 5 by means of a clamping tube by meansof clamping screws 20, 2U thread ing through the Wall of the tube on theother side. The tube 5 is provided with an insulating cover I9. A cap 2|with an insulating cover 22 may be threaded to the end of the tube, thecap and cover having aligned holes through which the cable passes, Inplace of the end construction indicated in Fig. 1, that shown in Fig. 5may be employed, in'which the insulating cover 23 of the tube 5 maycarry over the end of the tube in the form of a neck or flexible rubberhose 24 or some equivalent material, which hugs the cable E.

In the operation of the tool for welding purposes, the welding rod issimply wedged into the holder in any direction desired. The holder isparticularly adaptable for electrical Welding,
